Ecu's

I'm new to the honda world and I was wondering if anyone can answer me this...

...what ECUs can I use with my 94 gsr swap? I know I can use an OBD1 P72 (vtec) but I don't have one and it is very hard to find one that's for sale (and when I do find one, it costs a "grip"). So what's a good alternative? SOrry if this question has been asked before but I tried to use the "search function" but it would not let me do a seach on the word "ECU". Thanks for any help anyone can give me...

I'm not sure if you're being a "smart-ass" with this comment but if you are, it is most certainly not needed nor is it appreciated. If you read my post, I aknowledged the fact that I am aware that you can use a 94 GSR ECU. What do you think an OBD1 p72 (vtec) ecu is? Anyway, thanks...
